Sold ticket by consultant with false information

I'm writing to file a formal complaint about one of your consultants. I booked a ticket through WhatsApp since I saw on the internet that if you want to secure a seat, you must phone or use WhatsApp. The reason for the seat reservation is that the passenger is claustrophobic, thus it's critical that they find a seat that suits them.

However, prior to making the reservation, I asked the consultant twice if it was possible to make a seat reservation (screenshots attached). These messages were ignored. They responded to the third message I sent, saying that yes, it's possible, and that I should proceed with the payment. I paid and then inquired about how to proceed with the seat allocation. They responded as follows: "we regret that we dont have seat allocation on a mainliner it works on a first come first serve basis.“ Please see attached image attached.

The consultant was clearly pushing sales here and misled me, which is absurd given that I was forced to pay under false information. This is ridiculous and unacceptable. If the traveler is unable to find a comfortable seat, we will be forced to cancel the trip and forfeit the money, despite the fact that we were told we could reserve a seat! I was forced to book a bus ticket using false information by your consultant.
